Description

Technical Field

[0001] This utility model belongs to the field of steel furniture production technology, specifically relating to a cutting mechanism for steel furniture production with a lifting mechanism. Background Technology

[0002] A steel furniture cutting mechanism with a lifting system is a specialized piece of equipment used for cutting steel profiles. Its core function is to flexibly and precisely clamp the profiles or adjust the working height of the cutting blades through an electrically or hydraulically driven lifting system to meet the cutting and processing requirements of the profiles.

[0003] Chinese patent document CN221494376U discloses a cutting mechanism for furniture production with a lifting mechanism. It uses a screw to drive a limiting plate to lift and lower, adjusts the height of furniture parts to control the cutting depth, and uses anti-rotation strips and anti-rotation grooves to prevent the limiting plate from rotating. An auxiliary plate and abutment plate work together to fix the parts, and then a slider is manually pushed to move the parts toward the cutting machine to complete the cutting.

[0004] However, in the existing technology, the method of placing the profile on a movable work platform and then mechanically pressing its edges to clamp and fix it is prone to local deformation due to excessive extrusion during the processing of plate-shaped profiles, which affects the quality of the cut. Moreover, if the cutting depth is not properly controlled, it is very easy to damage the work platform itself. Therefore, a cutting mechanism for steel furniture production with a lifting mechanism is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting mechanism for steel furniture production with a lifting mechanism.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A cutting mechanism for steel furniture production with a lifting mechanism includes a material placement platform that suspends the section of the profile to be cut, a main lifting mechanism that can easily support and position the suspended section of the profile to be cut on the material placement platform, a clamp that can limit the position of the profile inside the main lifting mechanism, and a secondary lifting mechanism that can cut the profile as needed on the main lifting mechanism.

[0008] The material loading platform includes a frame, on which multiple rollers are movably mounted;

[0009] The main lifting mechanism includes a lifting component that enables the clamp to simultaneously support and hold the profile near the area to be cut;

[0010] The lifting component includes loading frames that are fixedly installed on both sides of the frame. Limit frames are fixedly connected to both sides of the loading frames. A low-level lifting frame is movably connected between the limit frames on the side of the two loading frames that are close to each other, and a high-level lifting frame is movably connected between the limit frames on the side of the two loading frames that are far apart from each other.

[0011] The main lifting mechanism also includes a transmission component that enables the low-position lifting frame and the high-position lifting frame to move synchronously in opposite directions, and an adjustment component that allows the clamp to be adapted to profiles of various thicknesses.

[0012] Preferably, the transmission component includes racks disposed on both sides of the loading frame and fixedly connected to the low-position lifting frame and the high-position lifting frame respectively. Shaft seats are fixedly installed in the front and rear of the loading frame. A rotating shaft is movably connected between the two shaft seats in the same loading frame. Two gears are fixedly connected to the outer surface of the rotating shaft.

[0013] Preferably, the adjusting component includes supports that are fixedly installed in the front and rear of the two sides of the high-level lifting frame, and a double-acting screw is movably connected between the two supports in the same longitudinal position. A handle is fixedly connected to one side of the double-acting screw, and two sliders are threadedly connected to the outer surface of the double-acting screw. A pull rod is movably connected below the sliders.

[0014] Preferably, the main lifting mechanism further includes two cylinders disposed between the frame and the low-position lifting frame.

[0015] Preferably, the limiting frame on the side of the two loading frames that are close to each other is slidably connected to the low-level lifting frame, and the limiting frame on the side of the two loading frames that are far apart from each other is slidably connected to the high-level lifting frame.

[0016] Preferably, the bearing seat is rotatably connected to the rotating shaft, and the rack and gear are meshed together, with the rack and gear being in similar lateral and longitudinal positions.

[0017] Preferably, the support is rotatably connected to the bidirectional lead screw, the high-position lifting frame is slidably connected to the slider, and the slider is rotatably connected to the pull rod.

[0018] The beneficial effects of this utility model are as follows: by separating the components in the fixture that can play a supporting and limiting role next to the cut, they can be moved with the low-position lifting frame and the high-position lifting frame. This allows the two lifting frames, which are driven by the transmission and adjustment components, to drive the fixture to easily clamp and fix profiles of different thicknesses. Combined with the independently lifting auxiliary lifting mechanism, the profiles can be precisely processed according to the set cutting depth after being placed on the rollers, effectively ensuring the quality of the cut and avoiding damage to the worktable.

[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0032] like Figures 1-7 As shown, a cutting mechanism for steel furniture production with a lifting mechanism includes a material placement platform 1 that suspends the section of the profile to be cut. The material placement platform 1 is equipped with a main lifting mechanism 2 that can conveniently support and position the suspended section of the profile to be cut. The main lifting mechanism 2 is equipped with a clamp 3 that can limit the position of the profile. The main lifting mechanism 2 is equipped with a secondary lifting mechanism 4 that can cut the profile as needed.

[0033] In this embodiment: the material placement platform 1 includes a frame 101, and multiple rollers 102 are movably mounted on the frame 101;

[0034] The frame 101 provides mounting positions for components such as the loading frame 201 and the cylinder 214. Multiple rotatable rollers 102, located outside the projection range of the main lifting mechanism 2 and with their axes on the same plane, are installed inside the frame 101 to support the profile to be cut, and make the profile easy to move within the cutting mechanism when the operator applies external force.

[0035] In this embodiment: the main lifting mechanism 2 includes a lifting component that enables the clamp 3 to simultaneously support and clamp the profile near the cutting point. The lifting component includes loading frames 201 that are fixedly installed on both sides of the frame 101. Limiting frames 202 are fixedly connected to both sides of the loading frames 201. A low lifting frame 203 is movably connected between the limiting frames 202 on the side of the two loading frames 201 that are close to each other. A high lifting frame 204 is movably connected between the limiting frames 202 on the side of the two loading frames 201 that are far apart from each other.

[0036] The main lifting mechanism 2 also includes a transmission component that enables the low-position lifting frame 203 and the high-position lifting frame 204 to move synchronously in opposite directions, an adjustment component that enables the clamp 3 to be adapted to profiles of various thicknesses, and two cylinders 214 disposed between the frame 101 and the low-position lifting frame 203.

[0037] The transmission components include racks 205 which are fixedly connected to the low-position lifting frame 203 and the high-position lifting frame 204 respectively on both sides of the loading frame 201. Shaft seats 206 are fixedly installed in the front and rear of the loading frame 201. A rotating shaft 207 is movably connected between the two shaft seats 206 in the same loading frame 201. Two gears 208 are fixedly connected to the outer side of the rotating shaft 207. The adjustment components include supports 209 which are fixedly installed in the front and rear of both sides of the high-position lifting frame 204 respectively. A double-acting screw 210 is movably connected between the two supports 209 with the same longitudinal position. A handle 211 is fixedly connected to one side of the double-acting screw 210. Two sliders 212 are threadedly connected to the outer side of the double-acting screw 210. A pull rod 213 is movably connected below the sliders 212.

[0038] The limiting frame 202 on the side of the two loading frames 201 that are close to each other is slidably connected to the low-position lifting frame 203, and the limiting frame 202 on the side of the two loading frames 201 that are far apart from each other is slidably connected to the high-position lifting frame 204. The bearing seat 206 is rotatably connected to the rotating shaft 207. The rack 205 that is close in the lateral position and the same in the longitudinal position is meshed with the gear 208. The support 209 is rotatably connected to the double-acting screw 210. The high-position lifting frame 204 is slidably connected to the slider 212. The slider 212 is rotatably connected to the pull rod 213.

[0039] The loading frame 201 provides installation positions for components such as the limiting frame 202 and the shaft seat 206. The limiting frame 202 limits the low-position lifting frame 203 and the high-position lifting frame 204 connected to it. The low-position lifting frame 203 and the high-position lifting frame 204 separate the components of the profile that the clamp 3 can contact at different heights within this cutting mechanism. The high-position lifting frame 204 can also install the linear guide rail 401. The gear 208, which is installed between two racks 205 connected to the low-position lifting frame 203 and the high-position lifting frame 204 respectively, via the rotating shaft 207, allows the low-position lifting frame 203 to move freely. 03. The high-level lifting frame 204 moves synchronously towards or away from each other in opposite directions due to external forces. The double-acting screw 210 installed in the high-level lifting frame 204 via the support 209 can simultaneously adjust the lateral position of the two sliders 212 connected to it and limited by the high-level lifting frame 204 when the operator rotates it by the handle 211. Through the pull rod 213 connected to the high-level clamping frame 303 at the lower end, the high-level clamping frame 303 is driven to rise and fall in the high-level lifting frame 204 when the sliders 212 move laterally. The low-level lifting frame 203 is driven to rise and fall as needed by the cylinder 214.

[0040] In this embodiment: the clamp 3 includes a low-position clamping frame 301 fixedly installed in front of and behind the low-position lifting frame 203 respectively. A first sealing plate 302 is fixedly connected below the low-position clamping frame 301. A high-position clamping frame 303 located above the low-position clamping frame 301 is movably connected between two pull rods 213 with the same longitudinal position. A second sealing plate 304 is fixedly connected above the high-position clamping frame 303. Multiple universal balls 305 are movably connected to both the low-position clamping frame 301 and the high-position clamping frame 303. A spring 306 is provided on the side of the universal ball 305 away from its own rolling end.

[0041] Both the low-position clamping frame 301 and the high-position clamping frame 303 are slidably connected to their respective universal balls 305, and the multiple universal balls 305 are arranged at equal intervals along the length direction of the low-position clamping frame 301 and the high-position clamping frame 303.

[0042] The low-position clamping frame 301 and the high-position clamping frame 303, which can contact the profile on the roller 102 after lifting and lowering, cooperate with the first sealing plate 302 and the second sealing plate 304 respectively to install the universal ball 305 and the spring 306 that continuously pushes the universal ball 305. The universal ball 305 contacts the profile first when the low-position clamping frame 301 and the high-position clamping frame 303 are lifted and lowered.

[0043] In this embodiment: the auxiliary lifting mechanism 4 includes a linear guide rail 401 fixedly installed on the high-level lifting frame 204, a slide 402 movably installed on the linear guide rail 401, a housing 403 fixedly installed on the slide 402, a hydraulic cylinder 404 fixedly installed inside the housing 403, a U-shaped frame 405 fixedly connected to the telescopic end of the hydraulic cylinder 404, and a cutting machine 406 fixedly installed below the U-shaped frame 405;

[0044] The housing 403 is installed by a slide 402 that can be precisely moved along the length of the linear guide rail 401. The connection relationship and operation mode of the linear guide rail 401 and the slide 402 are mature existing technologies in this field, so they will not be described in detail. The height of the U-shaped frame 405, which is slidably connected to the bottom of the housing 403 and on which the cutting machine 406 is installed, is adjusted by a hydraulic cylinder 404 installed in the housing 403. The cutting machine 406, which is composed of a drive unit and cutting blades, cuts the profile after the cutting blades rotate at high speed and come into contact with the profile.

[0045] Working principle: When this cutting mechanism is installed for steel furniture production, the profile to be cut is placed flat on the roller 102. The movable profile is positioned so that the part to be cut is initially below the cutting machine 406. Then, the cylinder 214 is initially activated to drive the low-position lifting frame 203 and the high-position lifting frame 204 to move towards each other until the universal ball 305 contacts the upper and lower sides of the profile and partially retracts into the low-position clamping frame 301 or the high-position clamping frame 303. At this time, the universal ball 305 will clamp the profile with a certain force. Since the part of the universal ball 305 that contacts the profile can roll, the operator can apply external force to the profile, which is slightly restricted in its translation at this time, so that the part to be cut can be accurately positioned below the cutting blade of the cutting machine 406, which has been lowered to a certain height with the high-position lifting frame 204. If the profile needs to be cut with a longer slit or even completely cut off, the preset slit direction should be completely parallel to the linear guide rail 401.

[0046] When the universal ball 305 moves toward the profile, the double-acting screw 210 can be rotated by the handle 211 to finely adjust the height of the high-position clamping frame 303 in the high-position lifting frame 204, so that the high-position universal ball 305 can contact the profile synchronously with the low-position universal ball 305, so as to ensure the support and clamping effect of the clamp 3 on the profile.

[0047] Once the profile position is determined, the cylinder 214 can be run again to drive the low-position lifting frame 203 and the high-position lifting frame 204 to move towards each other until the low-position lifting frame 203 moves to the upper side flush with the upper edge of the roller 102, and the universal ball 305 is completely retracted into the low-position clamping frame 301 or the high-position clamping frame 303. At this time, the low-position clamping frame 301 and the high-position clamping frame 303 will replace the universal ball 305 to press against the upper and lower sides of the profile respectively. The low-position clamping frame 301 can also provide support for the profile to prevent the clamped part from being lower than the upper edge of the roller 102 and deforming.

[0048] Once clamping is complete, the cutting machine 406 can be operated while the cutting machine 406 is running, either by controlling the slide 402 to move along the linear guide 401, or by operating the hydraulic cylinder 404 to adjust the height of the cutting machine 406, so that the cutting machine 406 can cut the profile as needed along the preset cut.

[0049] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
